The disclosures of all articles and references, including patent applications and publications, are incorporated by reference for all purposes. Other combinations are also possible as will be gleaned from the following claims, which are also hereby incorporated by reference into this written description.

This application claims the benefit of the filing date of U.S. Provisional Application Nos. 62/154,778, filed Apr. 30, 2015; and 62/270,663, filed Dec. 22, 2015, the entirety of the contents of these applications being hereby incorporated by reference for all purposes. The present teachings relate to an article which may be a member for providing baffling, sealing, reinforcing, or a combination thereof to an article of manufacture. The member may include a carrier; activatable material disposed on the carrier; and one or more carrier extensions extending from the carrier. The member may specifically be adapted to provide sealing, baffling or reinforcement within a structure's cavity. It is contemplated that the member may be applied (e.g., assembled) to various articles of manufacture such as boats, trains, buildings, homes, furniture, or the like. It has been found however, that the member is particularly suitable for application to automotive vehicles.

The article of the disclosure may further comprise any one or more of the features described in this specification in any combination, including the preferences and examples listed in this specification, and including the following features: one or more activatable material extensions may extend from the activatable material; one or more carrier extensions may extend into the activatable material; the carrier may include at least one hinge portion so that the carrier is flexible; the carrier may be comprised of a pliable material; the carrier may include one or more fasteners; portions of the carrier may be located in different planes from one another; at least one fastener may be located in a differing plane from at least one other fastener; the activatable material may be at least partially disposed on at least one fastener; the carrier may form a circle or a portion of a circle; the one or more carrier extensions may extend outward radially from the carrier; the carrier my split into two distinct portions; the carrier may include a receiving channel; the activatable material may have a curved profile; the activatable material may extend beyond an end of the carrier; the activatable material may be disposed on the carrier between one or more carrier extensions.

The carrier may have a longitudinal axis. The carrier may include one or more extensions. The one or more extensions may extend from a central portion of the carrier, which central portion may be in substantial alignment with the longitudinal axis. The one or more extensions may be arranged in a substantially perpendicular arrangement with the central portion of the carrier. Alternatively, the one or more extensions may extend from the central portion of the carrier at a skew angle. The carrier may include extensions that extend at both skew and perpendicular angles. The central portion of the carrier may bisect the one or more extensions. The central portion of the carrier may split into two distinct split portions where said split portions may be substantially parallel to one another or may be arranged in a non-parallel relationship. The split portions may be located at a terminating end of the carrier. The split portions may be formed such that they act as a fastener for locating the carrier in a desired location such that the split portions are located into and/or through an opening. The activatable material maybe located onto substantially the entirety of the carrier or alternatively may be located onto only portions of the carrier. The activatable material may substantially entirely enclose the entirety of the carrier. Alternatively, the activatable material may substantially enclose only portions of the carrier. The activatable material may be located onto any portion of the carrier that forms a fastener. The activatable material may substantially enclose any portion of the carrier which forms a fastener. Any portion of the carrier which forms a fastener may also be substantially free of any activatable material.

The carrier may include a plurality of fasteners which may be integrally formed with the carrier or separately formed from the carrier. The carrier may be flexible and thus may be formed to facilitate movement of the carrier along more than one axis. Portions of the carrier may be located in different planes from one another. A carrier including multiple fasteners may be formed so that a first fastener is located in a first plane and a second fastener is located in a second plane that is different from the first plane. The carrier may include one or more curved portions. The carrier may include hinge portions to facilitate flexing or may alternatively be substantially free of any hinge portions such that flexing is facilitated by the pliable material used to form the carrier and the material thickness. The plurality of fasteners may be arranged parallel to one another. The plurality of fasteners may be arranged such that a first fastener may be perpendicular to a second fastener. The carrier may have sufficient flexibility so that prior to insertion into openings, a first fastener and second fastener may be located parallel to one another (e.g., in a first position relative to each other), but during use and upon insertion into openings, the first and second fasteners are located in a non-parallel relationship relative to each other (e.g., in a second position relative to each other). The carrier may be arranged in an “M” shape. The carrier may be substantially continuous including no free end portions or one or less end portions. The carrier may include a t-shaped portion. The carrier may include a plurality of t-shaped portions. The carrier may include opposing t-shaped portions. The carrier may include an activatable material which may be located only onto select portion of the carrier. The activatable material may substantially enclose the entirety of the carrier. The activatable material may be located onto the fasteners. Alternatively, the fasteners may be substantially free of any activatable material located thereon.

The carrier may include one or more fasteners that are located so that they correspond with openings formed in a wall. The carrier may include a plurality of fasteners located adjacent one another to be located into a plurality of adjacent wall openings. The carrier may be formed so that a first portion of the carrier includes activatable material located on only a single surface of the carrier, whereas a second portion of the carrier is substantially surrounded by the activatable material. The carrier may include portions having a material thickness that is greater than the material thickness at other portions of the carrier. The portions having a greater thickness may be arranged in a position that is substantially parallel to or substantially perpendicular to a portion having a smaller thickness. The activatable material may extend beyond an end of the carrier. Alternatively, the activatable material may be substantially coextensive with an end of the carrier.

The carrier may include a portion that is curved. The curved portion may form a circle or a portion of a circle. Any extensions extending from the carrier may extend from a curved portion. The extensions may be substantially planar or may include a curved portion. The carrier may be curved and may include a plurality of extensions that extend outward radially from the carrier. A fastener may be included on one or more of the extensions. Alternatively, a fastener may extend from the carrier in a location that is distinct from the extensions. The fastener may extend in a direction that opposes one or more of the extensions. The fastener may be located adjacent an extension that opposes the remaining extensions. The activatable material may be located onto one surface of the carrier or onto multiple surfaces of the carrier. The activatable material may be located onto at least one surface of one or more extensions. The activatable material may be located onto exactly one surface of each extension. The fastener may include a first portion that rests adjacent an opening such that the first portion does not enter into the opening. The first portion of the fastener may be shaped so that it is too large to fits through an opening. The fastener may include a second portion that is located into and/or through an opening.

The carrier may include one or more hinge portions. One or more of the hinge portions may be free of any bending along the hinge until pressure is applied to one or more carrier portions adjacent the hinge portion. The hinge portions may be formed by portions of the carrier having a thinner cross section than adjacent portions of the carrier. The hinge portions may be formed by portions of the carrier that have a preformed curved shape. The hinge portions may include a fastener. The carrier may include a single hinge portion or may include a plurality of hinge portions. The carrier may be formed so that it is substantially planar until it is located into contact with one or more wall structures causing the carrier to form a shape that corresponds to the shape of the wall structures whereby the hinge portions facilitate the forming.

The activatable material itself may be formed to have a curved profile. In the event that the activatable material is not co-extensive with the carrier, the activatable material that extends beyond an end of the carrier may be curved. Any angle of curvature for one or more of the carrier and activatable material may be selected based upon the intended location of the device which may depend upon the shape of a cavity into which the device is to be located. The carrier and/or activatable material may be curved in a single direction or may be curved in multiple directions. The curve may form a substantially u-shaped or substantially v-shaped device.

At least a portion of the carrier may have a thin profile (e.g., a profile that is thinner than adjacent portions of the carrier). The thin profile portion may be such that it can be located in areas where the surface upon which the carrier is located must remain substantially flat. The thin profile portion may be connected to a fastener having a substantially thicker profile such that the thickness of the fastener assists in maintaining the thin profile portion in a flat position on a surface adjacent the fastener. The fastener may be shaped to include surfaces that lie in direct planar contact with a surface that lies adjacent an opening (e.g., an opening into which the fastener is located). The fastener may be an arrowhead fastener whereby one or more terminal ends of the arrowhead include surfaces formed to contact and exert a force on a surface adjacent an opening in wall.

The carrier may include a plurality of adjacent extensions with activatable material located therebetween. The extensions may be of differing length or may be substantially similar in length. A first extension having a first length may be located in between two adjacent second extensions having a length that is shorter than the first lengths. Alternatively, a first extension may have a first length that is shorter than the length of one or more adjacent extensions. The carrier may have extensions that extend away from one another or toward one another. The area between one or more extensions may be substantially free of any activatable material. Alternatively, the area between one or more extensions may be substantially filled with activatable material, or may be only partially filled with activatable material.

The carrier may be formed into an L-shape. An L-shaped carrier may include a fastener that extends from either side of the ‘L’. The carrier may include portions that form a y-shape and also portions that form a t-shaped. The y and t shape portions may substantially oppose one another. A fastener may extend from the t portion, the y portion, or both the y portion and t portion. The carrier may include a fastener located at a central location along the carrier. The portion of the carrier adjacent the fastener may have a thinner cross section than other portions of the carrier. The portion of the carrier adjacent the fastener may have a cross section that is thicker than other portions of the carrier. A first side of the carrier adjacent the fastener may have a thinner cross section than a second side of the carrier adjacent the fastener.

The carrier may have fasteners located at one or more terminating ends of the carrier. The carrier may include exactly two terminating ends and exactly two fasteners, one located at each terminating end. The carrier may have two fasteners located in a central portion of the carrier. The carrier may include two fasteners and both fasteners are located toward one side or end of the carrier.

The carrier may be c-shaped with curved edges or c-shaped with square edges. The carrier may have a serpentine or s-shape. The carrier may have a u-shaped, whereby the activatable material is not co-extensive with one or more ends of the carrier. The carrier may form a square. The activatable material may be located along the outside of the square, along the inside of the square or along both the outside and inside of the square. The carrier may be formed as a full square or as a partial square. The carrier may be formed as concentric circles or as portions of concentric circles. The activatable material may be located between the concentric circles. The activatable material may be located on only one surface of each concentric circle or on multiple surfaces of each concentric circle. The carrier may be substantially L-shaped and may include activatable material located surrounding the entirety of the carrier. The carrier may be formed as adjacent circles, each circle including one or more extensions or alternatively no extensions at all. The carrier may be formed as two opposing t-shaped portions.

Formation of the member of the disclosure may include a variety of processing steps depending on the desired configuration of the member. In any event, it is generally contemplated that the carrier and the activatable material may be manually attached to each other, automatically attached to each other, or a combination thereof. Moreover, various processes such as molding (e.g., compression, injection, or other molding), extrusion, pultrusion, or the like may be used to form the carrier, the activatable material, the one or more fasteners, the one or more carrier extensions, the one or more activatable material extensions, and such processes may be employed to attach these components together. One or more of the carrier and/or activatable material may be formed in processes disclosed in U.S. Provisional Application No. 62/074,237, incorporated by reference herein for all purposes.

The method of forming the member of the disclosure may comprise providing a carrier material and extruding and/or pultruding an activatable material on at least a portion of the carrier material, whereby the activatable material may be co-extruded and/or pultruded with the carrier material.

The activatable material 214 may include one or more activatable material extensions 218. The carrier extensions 216 may extend into the activatable material 214, such as the activatable material extensions 218. The member 210 may be elongated, as illustrated in FIG. 4. One or more fasteners 228 may extend from the carrier 212. The one or more fasteners 228 may be located at a first terminating end and/or second terminating end of the carrier 212. The one or more fasteners 228 may include a first pair of extensions 230. The one or more fasteners 228 may include a second pair of extensions 232. The fastener 228 may use only the first pair of extensions 230, the second pair of extensions 232, or both. The activatable material 214 may be extruded over a portion of the carrier 212. For example, the activatable material extensions 218 may be extruded over the carrier extensions 216. The activatable material 214 may be co-extruded with the carrier 212. In the embodiment as shown, the carrier extensions 216 and activatable material extensions 218 extend along the entire length of the carrier 212. However, it is contemplated that the carrier extensions 216, the activatable material extensions 218, or both the carrier extensions 216 and the activatable material extensions 218 may be intermittent along the length of the carrier 212.

FIGS. 6A and 6B illustrate section views of alternative exemplary members 310 with a partially circular carrier 312. The member 310 may include a carrier 312 and activatable material 314 thereon. The carrier 312 may have a circular cross-section, rectangular cross-section, or any other suitable shape for providing baffling, sealing, or reinforcement. A base section 311 may extend from the carrier 312. The carrier 312 may be partially circular, arched, have a radius, or curve along its length. For example 312, the carrier 312 may partially encircle about the base section 311. The carrier may include one or more carrier extensions 316. One or more carrier extensions 316 may extend from the carrier base section 311. The activatable material 314 may be placed on the one or more portions of the carrier 312. The activatable material 314 may include activatable material extensions 318. The activatable material 314 may be located on the carrier base portion 311 and the carrier 312. The activatable material extensions 318 may be disposed on the carrier extensions 316, such as the carrier extensions 316 extending from the base portion 311. The activatable material extensions 318 may extend from activatable material 314 disposed on the carrier 312, such as in the shape of fins. The activatable material extensions 318 may have one or more carrier extensions 316 therethrough or may be free of the one or more carrier extensions 316. If the carrier 312 has a rectangular cross-section, the activatable material extensions 318 may extend from the activatable material 314 located on a first surface of the carrier 312, as shown in FIG. 6A. If the carrier 312 has a circular cross-section, the activatable material extensions 318 may extend outward radially from just a portion of the surface of the activatable material 314 located on the carrier 312, as shown in FIG. 6A. The activatable material extensions 318 may extend from the activatable material 314 located on multiple surfaces of the carrier 312, such as both the first surface and second surface of the carrier 312, if the carrier 312 includes a rectangular cross-section, as shown in FIG. 6B. The activatable material extensions 318 may extend radially outward along the entire outer diameter of carrier 312, if the carrier 312 has a circular cross-section, as shown in FIG. 6B. The activatable material extensions 318 may be located across from one another, as shown, or in an alternating pattern. The partially circular carrier 312, the carrier extensions 316, the activatable material extensions 318, or a combination thereof, may provide for more rapid activation of the activatable material 314. For example, if the activatable material 314 is heat activated, the dispersion of the activatable material extensions 318 allow the activatable material 314 to reach an activation temperature more rapidly than if the activatable material 314 were placed in a solid, continuous manner along the length of the carrier 312. The activatable material 314 may be extruded over the carrier 312 or may be co-extruded with the carrier 312. The carrier may include one or more fasteners 328. The fastener 328 may include barbs 331 for retaining the fastener to a wall, panel, or other surface. The barbs 331 may engage with a receiving hole (not shown). The one or more fasteners 328 may be integral with the carrier 312. The carrier 312 may split into two or more portions along at least a portion of its length. For example, the carrier 312 may be split into two sections along the length of the one or more fasteners 328.
